Discovery is the formal process by which the prosecution discloses non-privileged information relevant to a criminal investigation prior to trial. It provides the basic foundation for accuracy and reliability in a criminal case. It is a crucial safeguard that helps make our legal system more transparent, ensures a fairer procedure, and helps protect against wrongful convictions. All other aspects of our constitutional system, such as due process and assistance of counsel, depend on complete discovery.

The record of wrongful convictions in this country has demonstrated that exculpatory evidence can be withheld for years, even decades, while an innocent person sits in prison. Whether the state fails to disclose evidence inadvertently or intentionally, clear rules about what is subject to discovery – and clear consequences for failure to disclose discoverable information – minimizes the risk of these mistakes.

Uniform, mandatory, and enforced discovery laws are needed to protect against wrongful conviction. Best practices include open-file discovery, mandatory and automatic disclosures, appropriate timing, certification of exchange, and remedies for noncompliance. These practices have been endorsed by knowledgeable expert groups such as the American Bar Association, the National Conference of Commissioners for Uniform Law, and many state criminal justice commissions.
